TpCallContent

struct TpCallContentClass

tp_call_content_init_known_interfaces ()

void tp_call_content_init_known_interfaces
(void);

Ensure that the known interfaces for TpCallContent have been set up.
This is done automatically when necessary, but for correct
overriding of library interfaces by local extensions, you should
call this function before calling
tp_proxy_or_subclass_hook_on_interface_add() with first argument
TP_TYPE_CALL_CONTENT.

Since 0.17.5

TP_CALL_CONTENT_FEATURE_CORE

#define TP_CALL_CONTENT_FEATURE_CORE

Expands to a call to a function that returns a quark for the "core"
feature on a TpCallContent.

One can ask for a feature to be prepared using the tp_proxy_prepare_async()
function, and waiting for it to trigger the callback.
